About Blacklist Lookup

The blacklist check will test a mail server IP address against over 100 DNS based email blacklists. ( Commonly called Realtime blacklist, DNSBL or RBL).

If your mail server has been blacklisted, some email you send may not be delivered. Email blacklists are a common way of reducing spam.
